A line plot of health related quality of life on the vertical axis, labeled 0, 0.5, 1.0, against health state duration in years on the horizontal axis, not labeled. A point is marked on the horizontal axis as death. The line starts at the vertical axis where quality of life = 1, is horizontal for a while, then slopes sharply downwards until quality of life = 0.5, then is horizontal for a while, then slopes down again to meet the horizontal axis, quality of life = 0, at death. The space between the axes and the line is shaded.
